What was Griffith’s explanation for the experiment’s results

Serjik [45]

Answer:

Griffith concluded that the R-strain bacteria must have taken up what he called a "transforming principle" from the heat-killed S bacteria, which allowed them to "transform" into smooth-coated bacteria and become virulent.

Select one lettered organelle and:

WINSTONCH [101]

Part A:
A - cell/plasma membrane.
B - Nucleus
C - mitochondrion

Part B:
A - (cell membrane) regulates what enters and leaves the cell.
B - (nucleus) controls cell activities or contains the genetic codes.
C - (mitochondrion) respiration or energy release or production of ATP.

Part C:
Photosynthesis
Production of cellulose
Produces chlorophyll
Producing its own food

Compare and contrast light microscopes, scanning electron microscopes, and transmission electron microscopes. Sort each statemen

podryga [215]

Answer:

Light microscope:

use a beam of light to produce magnified images
can be used to examine living cells and tissues

Scanning electron microscope:

use a beam of electrons to produce magnified images
can be used to examine DNA
can be used to examine cells

Transmission electron microscope:

use a beam of electrons to produce magnified images
can be used to examine DNA
can be used to examine cells

Explanation:

Light microscope: is a commonly used microscope also known as compound microscope. Magnifies images from 40X upto 1000X. It uses ray of visible light to produce a magnified image. The light microscope can be used to view specimen of both living and dead cells or tissues. However, it doesn't give a detailed view of a specimen like electron microscope.

Scanning electron microscope: It uses electron beam as an illuminating source. It has a much higher resolving power than light microscope because it uses electrons instead of light. It magnifies object upto 500000 times the actual size. Internal structures can also be viewed. However, only dead specimen can be used because the beam of electrons can kill the cells. They are of two types:

Scanning electron microscope(SEM): an electron beam passes over the specimen's surface and displaces electrons which are then focused on a screen to form an image. Images appear in 3-D
Transmission electron microscope: electromagnets magnify the image by passing beam of electrons through a thin specimen. Images appear in 2-D
